to the accompanying drawings, which form a part thereof. I v

The present invention relates to coke ovens and the like and particularly to improve the construction and arrangement of the burners employed in such ovens.

In large capacity coke ovens the burner nozzles or twyers need to be placed at intervals along a combustion space or spaces extending far intothe oven body. These twyers and nozzles require considerable attention from time to time and in many cases it is highly undesirable to provide burner chambers large enough to allow of the nozzles being adjusted or repaired i'n si'tu. Moreover where such chambers are prox'ided the operation of inspecting or repairing the twyers in place without inter: rupting the operation of the oven is a serious one .on account of the high temperatures to which the attendant is exposed.

The main objects of the present invention is to provide a construction and arrangement in which the various twyers or nozzles and connections to them can be quickly withdrawn and inspected and if defective can be replaced by a new set of twyers and connections, all without mat rially interfering with the-operation ofth ovenstructure of. which they form a part.

The various features of novelty which characterize the invention are pointedout with particularity 1n the claims annexed to and fflrmlng a part of thls spe'clfieation.

For a better understanding'of the invention however reference may be had to the accompanyin drawings anddescriptive matter in Whic I have illustrated and described forms in which my invention may be embodied.

is an elevation of an upper burner construction generally similar to the construction shown in Figs. 5 and 6. ,Fig. 8 is a view taken similarly to Fig. 4, but on a larger scale and showing a modified burner nozzle construction. Fig. 9 is a plan View of the nozzle construction shown in Fig. 8. Fig. 10 1s a view taken similarly to Fig. 8, but

showing a construction differing somewhat from that of Fig. 8. Fig. 11 is a plan View of the construction shown in Fig. 10.

In the drawings, and referring first to the constructions shown in Figs. 1 to 4 inclusive, A represents the masonry wall of the coke oven structure, which has formed in it a plurality of coking retorts D 0 'en at top andbottom and heated at the sidiis by heat- 1n flues D, which are connected at their on s by passages 13 and B res ect'vely with regenerator chambers B and generator chamber B has an inlet-outlet passage B connected to a chimney C at one side Each re of the oven, and eachchamber B has an inlet-outlet passage B connected 'to the chimney C. Suitable dampers and valves (not shown) placed in the upper ends of the c imn'eys C and G and in the air inlet pi es C connectedto the lower ends of the ChlIIlneys rovide for a flow from the chimney G into t e regenerator chamber B, and thence through passages B, flues D, passa es. B", through the regenerator chamber B from thence it passes into the chimney C, or in a reverse direction if desired. I

The general arrangement of the retorts and heatin system therefor disclosed but not claime ter of my copending a plication Serial No. 398,902, filed of even ate herewith. It is to be understood moreover that the present invention is capable of usewith many different systems.

Atthe upper ends of the flues D are burner chambers D and similar chambers are located at-the lower ends of the flues. In. the storm shown in Figs. 2, 3 and 4 the burner chambers pro er are connected to the adjacent flue spaces y narrow passa es Di. In each burner chamber there are .pre erably a pair of burners E which are inserted in herein forms the subject mat burner E comprises a body member or main -.fuel chamber usually' formed of metal and .has secured to'it at its outer end a flangethe upper ends of the .bosse mission of fuel from the burner chamber as shown.

from the burner body.

likeportion E forming adoor for closing the burner chamber D operation of inserting andwithdrawingl the To facilitate the burners are referably provided'with ement when any burner becomes defective it can readily be withdrawn and a new burner inserted without other than temporary interruption of the'burner. -The defective burner can of w eels. y this arrang course be removed to a proper place for'adjustment or repairs. From the upper side of the burner chamber or body extends the nozzles or twyers-Eiipreferably formed of refractory material as fire clay. These, in the form shown in Figs. 3 and 4, are inserted in hollow bosses E extending upward The nozzles are held in place by removable ca pieces E in s E and the adinto each nozzle is controlled by perforated plate E located at the lower end of the nozzle. In the preferred construction shown, there is one nozzle E for each ofthe heating flues -D, and, in the form shown in Figs; 3-and 4, the nozzle of each burner,

projects to the mouth of" the heating flue through'the narrow slit D In the;arrangement shown in Figs. 5. and 6, provision is made for regulating the' character of the flame produced. The regulating means comprising specially shaped fire-brick ortile F each having two horizontal portionsF and F connected by a bracket- .or-

tion F. The horizontal portions F an F thus'uniteto form an a-l'r chamber F beneath the upper end of a nozzle E? into which lead the air ports Bf", which, in the particular arran ement shown in Fig. 5, lead to the fines rom both sides instead of from one side, ,a-s'in the construction shown in Figs. 1"to'4 inclusive; In this form also the burner chamber is of the same width from top to bottom.v By l'suitably shapin the up er ends of the brick ortile F an particu arly the passages'leading from this chamber into the flue and 'sha e of the air stream surrounding the nozz e and thereby the character and fha e of' the'flame produced can be reguate The construction shownfin Fig. 7 differs from that of Figs. 5 and 6 in that the burner shown is an upper burner and-has the wheels E connected to the burner body by brackets E. In this case the wheels run trolley fashion on thelower flanges G of an'I beam 1 G. secured against the upper wall of the upper burner chamber. .In this form of the invention, the brick or tile F are supported by flanges E formed on the lower ends of t e boss E which, in this form of the inven-' proper, [the direction i the bu tion, pro ect downwardly. Similarly, each nozzle E, in this form .ofthe invention, is provided with a collar at its upper end which. revents it from dropping through shing E A tight joint between the nozzle and burner body a packing of sand or' regulating diaphra may be obtained by clay. The gas flow is of course located above the. upper ,en' of the nozzle ET in this form of the invention, and the nozzlea'nd diaphragm are inserted through the hole normall closed by the eoverE. It will be observe that both in thisconstruction as well as that shown in Figs. 5 and 6, the tiles F are readily removable, but are positively and definitely held in place by suitably forming engaging surfaces between them and theburner r0 er. 1

The nozzle 1 instead'of being of the simple form shown in Figs. 3, 4, 5 and 6, may 'be'modified in-variousways. In the constructions shown in Figs. 8 and 9 for with any attachmentsnecessary or desirable to shape or control the flame maybe readily putin' place or removed without exposing the attendants to excessive temperatures or ebrick F, and the flange porinterrupting the operation of the oven structure in an a precia'ble degree; The provision of t e oor flange E assists greatly as the formation of a tight closure can there-' by be quickly had. 'I e joint between the door and oven wall proper may be packed with clay or the like if necessary. An advantage of the arran ement'sho'wn is that the burner body whic ordinaril is made of much less refractory materia than the twyers is located at the side of the burner chambers remote from the combustion s ace or spaces which of course only be in w ere the air and gas mix, 11. e. the ends 0 the flues. v In the construction shown in Figs. 1 to 4 inclusivethe burner bodies are directly exposed to direct radiation from the hot gases through the narrow slit like assa es D and in the construction where t e bricks F are employed they serve of course to protect the burner body.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with a coke oven havv insertible ing an elongated burner chamber open at one side of the chamber to a combustion space, an elongated burner body'located in nozzlesor twyers supported by and removn able and insertible with said burner body, said twyers extending from the burner body to said combustion space, bodies of refractory material supported on said burner body and surrounding the twyersto influence the form and direction of the air currents blowing by the flame ends of the twyers, said bodies serving also to protect the burner body from heat from the combustion space.
